UTTO rmenians MACi-IIN Beit knownthat I, ALLEN JOHNSTCN,3. citizen ofthe United States, residing in Ottumwa, in the county of Wapello and'State of Iowa, haveinvented a newand, useful Improvement inButton-Attaching Machines, of which the following is a specification. gI

This invention relates to improvements 1n button attaching machines andmore partic- .ularly to machines for attaching shoe but tons to shoes. v

-.Objects of the invention are to provide a machine of thetypeaboveindicated which isof simpleconstructiom of high "capacity andwhichv automatically accommodates itsizes- 1' Another object of. theinvention isto provide a button attaching machine in which self .totheattaching of buttonsof different thewire, which forms theattachingTstaple, is fed through the eye ofthe button severed andformedinto a staple at one station and the button with its staple moved toanother station where the staple is clenched to the shoe or otherarticle, thereby providing ample time for the operator to place the shoeor other article to which the buttons are to be attachedin properpositionand without danger of displacing the buttons during the wirefeeding and staple forming operation. 7 a

i The inventionfurthermore consists in the improvements in the parts anddevices and in'the novel combinations of theparts and devices as herein,,shown, -'described and claimed.

In the drawing specification, Figure 1 is a top plan-view of a machineembodying my improvements, parts being broken away and other parts beingshown in section to better illustrate the mechanism. Fig. 2 is asideelevation of the machine shown in F ig, 1, several of the pa'rtsbeingshownin se'ctiontobetter 1llus- I trate their construction andoperation. Fig.
